Thank you very much Mike , at last I understand what the aspens are. I began some years ago thinking the aspens are betula, more recently concluded they could be populus tremula but I too saw the difference: the trunk of my populus isn't white...

No, Betula sp. is birch, and not all birch have white bark. Populus tremuloides have a creamy-white/green bark, but Populus grandidentata have more of of an orangey/green bark. Other poplars like the cottonwoods can vary greatly. One thing all Populus sp. in North America have in common (except balsam poplar - there's one in every crowd) is a flat leaf stalk or petiole. This is the stem that goes from the base of the leaf to the branch. The flat petiole makes the leaves rustle in the breeze, hence names like 'trembling aspen' or 'quaking aspen'.

Okay, that's enough dendrology for the day.

I'll copy your very useful lesson in "populology" in order to study it later, as thanks I post the birch (it's a she, a girl) of my hortulus secretus portrayed in july and in october, in the mist and under a snowfall.

I like the verdant greens of spring, but winter is running a neck and neck tie...they're all beautiful.

Shooting the green picture last year (not exactly in spring, but in july at 1300m the greens are still fresh) I got (I don't know how) a meniscus inflammation that stopped me until november... and at present I can still hear an ominous "click cluck" coming from the knee...

It's an interesting landscape view that is presented in a pretty unusual way - centered as such. I take the subject as being the small tree on the log, and I do wish it would stand out more via the kind of exposure treatment of the whole photo. The unusual framing works pretty well for me, but I think it can be improved over what you have. The scraggly branches in lower right and left don't serve the picture much. This photograph is kind of fun and quirky. I am concerned that the water looks vaguely wrong in color or texture. I don't know why. Overall I do like it.
